Characteristics of van der waals forces
WebLondon dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent—polar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are. For example, bromine, \text {Br}_ {2} Br2 Web3. van der Waals forces. 4. dipole-dipole forces. 5. H-bond.

Web1. distinguish characteristics of London Dispersion Force Answer: The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. Following are the characteristics of Van Der Waal forces. 1. These forces are additive. 2. They are weaker than ionic, covalent bonds. 3. Van Der Waals forces are not directional. 4. They work in a short range. The interaction increases when molecules are closer. 5. These forces are independent of temperature. The … See more Electrons are distributed throughout an atomor molecule. Moreover, electrons are always moving. At any moment there can be uneven … See more Primarily there are three types of Van Der Waal forces. Following are the list of those. 1. Dipole-dipole Forces Dipole is a polar molecule in … See more The strength of these forces usually ranges between 0.4 kJ/mole and 4 KJ/mole. Moreover, they act over a distance of less than O.4 nm. However, the net effect of these forces is repulsive because electron … See more The strength of these forces mainly depends on the following factors. 1. Size of the Molecule-If you look at the periodic table, you will see that the boiling point of noble gases increases, as you go down. It happens because … See more

WebVan der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors. It is more difficult for short, bulky molecules (with substantial amounts of branching) to lie close together (compact) compared with long, thin molecules.
